I’m a Lead Backend Engineer with 7+ years of experience designing and building scalable, high-load systems across fintech and IoT domains. I focus on system architecture with a strong emphasis on microservices, real-time processing, and distributed systems.

In my current role as a SmartGas Global Senior Software Engineer (Backend / Architecture), I designed and implemented IoT microservices (Node.js) for real-time fuel station control using WSS, TCP, and HTTP. I drive decomposition of monoliths into scalable microservices architectures and build fault-tolerant systems for real-time fuel and financial transaction processing.

Across my contract and freelance international projects, I’ve developed and maintained backend platforms and API ecosystems—building OpenAPI platform services for banking, integrating via API gateway, and working with IBM API Management. I also led architecture and scaling efforts as a Lead Backend Developer / Team Lead using PHP (Laravel), Vue.js and related services.

Earlier at Centras Capital Group, I led the transition from a Yii monolith to microservices (Laravel, Go), migrated data (MySQL/Oracle → PostgreSQL), and contributed to a DWH using AWS Redshift, S3, and Lambda. I consistently improve reliability and observability, introducing practices like feature flags, outbox pattern, and structured logging.
